Megan asked, "Has anyone ever had a problem with the mouse injuring the ferret? Are there any bizarre diseases that can be passed from a mouse deemed snake food to a ferret (vaccinated, of course)?" I don't know about mice, but when Lily was bitten on the toe by one of our pet rats when she managed to get up on their cage, it took weeks for her toe to heal, even though she received several kinds of anitbiotics. I think many of the lab/pet/feeder rat bacteria have become highly drug resistant, and rats have very 'dirty' mouths (like humans). Quite a few of these rats suffer from a disease similar to tuberculosis--we couldn't find out for sure whether ferrets can be infected by that organism, but it is very hard to treat in rats.
